Example 24.4, using 2a = 8.0 cm and y = 8.0 cm and x = 18 cm; and Calculate A, B and C.

Example 24.4:

An electric dipole consists of two charges of equal magnitude and opposite sign separated by a distance 2a as shown in the gure. The dipole is along the x axis and is centered at the origin. (A) Calculate the electric potential at point P on the y axis. \f(C) Calculate V and E at a point on the x axis far from the dipole. 2k qa 2k qa Vp = lim (x> > a) x> >a x2 -a X 2 dV d 2k qa E = P dx dx x2 d =2k ga R dx 1 2 + - X - q 4k ga a- = (x> > a) X
